The current predicted attendance is 16,470, with 16,500 need to unlock the next donation of £2,500 by Regular Cleaning for the Charlton Athletic Community Trust.

CACT CEO Jason Morgan said: “A huge thanks to fans for reaching the first target. Let’s hope others can be achieved so this creates a fantastic atmosphere and big crowd to support the team tomorrow.”

Steve Clarke, who represented Charlton Athletic Supporters Trust at a recent Fans’ Forum meeting about Saturday's game, said: "It is good to see we’ve hit the first target, let’s hope fans can push on and make 16,500 on the day."

To celebrate the anniversary and 25 years of the Charlton Athletic Community Trust, the club is also donating 25% of home ticket revenue from the game along with 25% of matchday programme sales to the charity.
